swL2PortStFragments
Module: SW-LAYER2-PORT-MANAGEMENT-MIB
OID (symbolic): SW-LAYER2-PORT-MANAGEMENT-MIB::swL2PortStFragments
OID (numeric): 1.3.6.1.4.1.326.2.20.1.2.2.2.28.2.4.3.1.14
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: This counter is incremented once for every received packet which meets all the following conditions: 1. Packet data length is less than 64 bytes or packet withourt SFD and is less than 64 bytes in length. 2. Packet has invalid CRC. 3. Collision event, late collision event and receive error event have not been detected.
What is swL2PortStFragments?
Counts undersized (under 64-byte) frames received on this port that also have an invalid CRC, typically caused by a collision that was cut off mid-transmission - a sign of network contention or a duplex mismatch on that segment.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.326.2.20.1.2.2.2.28.2.4.3.1.14 snmpwalk -v2c -c public <target> SW-LAYER2-PORT-MANAGEMENT-MIB::swL2PortStFragments
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.326.2.20.1.2.2.2.28.2.4.3.1.14.1 snmpget -v2c -c public <target> SW-LAYER2-PORT-MANAGEMENT-MIB::swL2PortStFragments.1
